Pregnancy is such an exciting time, with so much to do and so many things to find out. That is why we’ve gathered together all these useful online tools for pregnancy, some will help you work out all the important dates in your pregnancy timeline, while others are a fun way to predict what your new baby will be like.

All these online calculators and tools are based upon average dates for example for length of pregnancy or your menstrual cycle. As you know, we are all different; for example our menstrual cycles vary from woman to woman and often from month to month.

So always take the results of any of these calculators as a rough guide rather than a 100% definite fact.

These calculators do not represent qualified medical guidance and should not be regarded as medical advice. If you have any questions about your pregnancy or baby you should always ask a qualified medical practitioner.

    If you are trying to get pregnant, a really good place to start is with an ovulation tool. This tool will help you to understand when in your menstrual cycle that you actually ovulate, to maximise your chances of becoming pregnant.

    This online ovulation calculator tool will show you the best days in the month where you are most fertile, and therefore most likely to become pregnant.

    As this is based on average women is can only be taken as a guide to when you are most fertile. There are other ways to try and identify when you are most likely to conceive. Some women find that keeping a record of their temperature throughout the month is helpful, as your temperature rises by one or two degrees just after ovulation. You can buy special ovulation thermometer to help you with this.

    The most accurate way to know that you have ovulated is by using an ovulation test kit. These kits test the level of Luteinising Hormone in your urine. The level of this hormone rises just before ovulation so the test can tell you telling you when that you are about to ovulate.

    A pregnancy wheel, or gestation calculator is traditionally a card or plastic gadget which your doctor or midwife uses to calculate the key dates of your pregnancy. They will use it to work out when each of your trimesters begins, when you should have your ultrasound scans and your ultimate due date.

    You can buy one of these Pregnancy Wheels for yourself quite cheaply, or you can also try using an online Pregnancy Wheel. This will give you an idea of all the crucial dates from when you can expect your foetus to implant, when you can expect to have your scans.

    Important note: The answers given by the Pregnancy Wheel that is linked to here is based on US medical conventions. The testing dates or tests suggested may be different or may not be widely available in other countries.

    Once all your dates in order, you may be wondering what the sex of your new baby will be.

    It is possible to identify the gender of an unborn baby at around 3 months at your ultrasound scan, assuming that baby co-operates by lying at the correct angle! By 20 weeks the sex can usually be found with 99% accuracy.

    However in the days before scans, there were lots of folklore and old wives’ tales about how to find out whether you were carrying a boy or a girl. These should always be regarded as a bit of fun, but here are 17 ways to predict the gender of your baby at home.

    One of the ways to guess the sex is the Chinese Gender Predictor Chart, which is based upon the mother’s age at conception, and the month that the baby was conceived. We’ve also created a Chinese gender predictor calculator where you can put in these figures and find out what this ancient method thinks that your baby will be.

    The Mayan gender predictor is another way to predict the sex of your baby. It is no more scientific than the Chinese prediction chart, but if you want to try this have a go at the Mayan Gender Predictor Calculator which also uses the mother’s age at conception and the month of conception, similar to the Chinese one.

  13. Child’s Adult Height Predictor

    Another thing that you may wonder about your baby is, how tall they are likely to grow to.

    If you would like an estimate of their future adult height try out our Child’s Adult Height Predictor Calculator. This is based upon the calculation given in the “Red Book” which is given to each family in the UK which contain the child’s health records up to the age of 7. It is due to be digitised in the next few years.

    Of course this calculation does not take into account any health issues that might affect a child’s height, and should only be taken as a rough estimate – according to this my two boys should both the same height, but they certainly are not.
